While I do want to find a pro to check out this console, I do want to start learning about this type of technology. Working in radio I use mainly digital. Any suggestions on a starting point?

Thank you MattTech

I'm currently trying to find someone in my area that can work on this console. It looks like I made a typo in the model. It is an RPC-21S not a 215.

I just purchased a Packard Bell RPC-215 from a flea market and was told that it worked. I can get it to power on but cannot get any sound or tuning through the AM/FM tuner. I cannot seem to find any information about this model online. Any help that someone might have would be much appreciated! This...
